Application of MWCNT to Study Azometine-H by Cyclic Voltammetry

摘要

This work deals with the electrochemical study of Azometine-H by mean of cyclic voltammetry using a carbon paste electrode modified with multi-wall carbon nanotubes, MWCNT, and β-Cyclodextrin. The results obtained evidence that it possible to follow the electrochemical evolution of the azometin-H at pH 7.0 and that the use of an electrode modified with carbon nanotubes improved the electrochemical response, favoring the electron transfer and increasing the oxidation peak's current, as compared with a conventional carbon paste electrode. Further, it was found that the azometine-H displayed an adsorption process associated to the interaction between the compound under study and the β-ciclodextrin.
